#473 refactor[rs_controller]: Use nightly fmt to reorganize imports Pull request opened by SVilgelm Reorganize module imports across several files to use grouped and brace-formatted use statements for better readability and consistency. Add a Makefile fmt target that enforces use of the nightly toolchain and runs

cargo +nightly fmt --all

to standardize formatting in CI and local development. These changes improve code consistency, maintainability, and make it easier to apply automatic formatting across the repository. --- This is part 1 of 2 in a stack made with GitButler: • 2 #476 • 1 #473 👈 flyteorg/flyte-sdk
